Registering a domain name and hosting one is sometimes mistaken by a lot of people to be one and the same thing. They are actually two separate services - the domain name registration is the actual name and nothing else, while the hosted domains feature refers to the number of already registered domains that you can accommodate within the same web hosting account and have website files and e-mails for them. Your websites will work in exactly the same way no matter if the domains are registered and hosted in one place or are registered with company A and directed to company B. Simply registering a domain without hosting it will grant you ownership, but will not enable you to have a web site unless you host this domain in some account so that records for it are set up and it starts opening the information from that account.
